Vulnerability Assessment vs Penetration Testing: What's the Difference?

A vulnerability assessment identifies, classifies, and prioritizes known weaknesses across systems, typically using automated scanning supplemented by manual verification. It answers the question: what vulnerabilities exist?

Penetration testing goes further by actively attempting to exploit discovered weaknesses to demonstrate real business impact. It answers the question: what can an attacker actually achieve?

Many organizations run frequent vulnerability assessments to maintain baseline hygiene, then commission a deeper penetration test annually or before major releases to validate that critical systems hold up against determined, skilled attackers.
